IMPROVED REFRIGERATOR.

Specilcation forming part of Letters Patent No. 102,064, dated April 19, 1870.

This invention relates to a new and useful improvement in refrigerators for keeping food (or articles designed for food) at a low temperature, and consequently from decay; and it consists in providing the refrigerator Vwith double doors, which swing simultaneously with each other, and in the arrangement ol' the shelves thereon, and in the method of disposing of the gases and providing for ventilation, as hereinafter more fullyT described.

In the accompanying drawings, Figure l is a front view With one ofthe doors open. Fig. 2 is a horizontal section of Fig. 1 on the line x Fig. 3 is a vertical section of Fig. 1 on the line Similar letters ot' reference indicate corresponding parts.

.In thisexample of my inventionv the refrigerator is made with two front outside doors, each door having another inside door or shutter connected therewith at right angles, so that when the outer door is opened the inner door closes the front and excludes the outer lair, as seen in Fig. 2.

A is the outer door, and B is the inner door.

C represents the shelves, which are made to t the angle formed by the combined doors,

the outer edges of the shelves forming arcs of circles described from the center of the hinge of the door. By this arrangement, when the outer door is opened, the shelves attached thereto are (with the article on the shelves) withdrawn from the refrigerator, and the inner door closes the aperture, thus preventing the escape of the cold air and the entrance of thewarmer air from the outside.

D is the ice chamber, directly over the shelves, with openings into the space beneath for the descent of the cold air. from the ice passes to the center, and is discharged from the pipe E. There are two airspaces, F and G, around tbe ice-box. The outer one, F,is for conveying the Warm air and gases from the inside to an outside pipe, H, through the tube I, which pipe is open at both ends, and arranged so that a draft is created through it, which carries upward the .warm air and gases from the interior. The inner space, Gr, around the ice-chamber, allows the cold air to descend. l

The advantages of this arrangement must be obvious to all.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In combination with a refrigerator having ice-box D, the doorsA B,provided with shelves C, as and for the purpose specified.

2. The outside space, F, around theicechamber, tube I, and the outside pipe, H, combined and operatingsubstantially as and for the purposes described.
